[PATCH] PM / devfreq: Move struct devfreq_governor to devfreq directory

[PATCH] PM / devfreq: Move struct devfreq_governor to devfreq directory

[Chanwoo Choi]

This patch moves the struct devfreq_governor from header file
to the devfreq directory because this structure is private data
and it have to be only accessed by the devfreq core.

When I applied it to 4.11-rc5, there is no any conflict.

I used the 'git am' command. Also, As I knew,
after releasing the 4.11-rc1, there was no patches
related to both drivers/devfreq/governor.h and include/linux/devfreq.h
